The ophthalmic applications of a diffractive trifocal lens design with adjustable add powers and light distribution in the foci are investigated. Axial PSFs of the trifocal lenses are calculated and analyzed as a function of the design parameters and the eye pupil size. The optical performance in actual eyes is also simulated by including the measured ocular wave aberration functions of human eyes in the calculation of transverse and axial PSFs, and Strehl ratio axial variation. The effect of the polychromatic character of natural light has also been considered. The calculus and simulation method of this paper can be applied for the design and analysis of any other kind of diffractive or refractive multifocal contact or intraocular lens.
研究了一种具有可调节附加屈光度和焦点光分布的衍射三焦点透镜设计的眼科应用。计算并分析了三焦点透镜的轴向点扩散函数（PSF），作为设计参数和眼睛瞳孔大小的函数。通过在横向和轴向PSF以及斯特列尔比轴向变化的计算中纳入人眼的实测眼波像差函数，还模拟了实际眼睛中的光学性能。此外，还考虑了自然光的多色特性。本文的计算和模拟方法可应用于任何其他类型的衍射或折射多焦点接触镜或人工晶状体的设计和分析。
